Currently, our batchable binned items are stored in a hash table that
maps bin key, which includes the batch set key, to a list of entities.
Multidraw is handled by sorting the bin keys and accumulating adjacent
bins that can be multidrawn together (i.e. have the same batch set key)
into multidraw commands during `batch_and_prepare_binned_render_phase`.
This is reasonably efficient right now, but it will complicate future
work to retain indirect draw parameters from frame to frame. Consider
what must happen when we have retained indirect draw parameters and the
application adds a bin (i.e. a new mesh) that shares a batch set key
with some pre-existing meshes. (That is, the new mesh can be multidrawn
with the pre-existing meshes.) To be maximally efficient, our goal in
that scenario will be to update *only* the indirect draw parameters for
the batch set (i.e. multidraw command) containing the mesh that was
added, while leaving the others alone. That means that we have to
quickly locate all the bins that belong to the batch set being modified.
In the existing code, we would have to sort the list of bin keys so that
bins that can be multidrawn together become adjacent to one another in
the list. Then we would have to do a binary search through the sorted
list to find the location of the bin that was just added. Next, we would
have to widen our search to adjacent indexes that contain the same batch
set, doing expensive comparisons against the batch set key every time.
Finally, we would reallocate the indirect draw parameters and update the
stored pointers to the indirect draw parameters that the bins store.
By contrast, it'd be dramatically simpler if we simply changed the way
bins are stored to first map from batch set key (i.e. multidraw command)
to the bins (i.e. meshes) within that batch set key, and then from each
individual bin to the mesh instances. That way, the scenario above in
which we add a new mesh will be simpler to handle. First, we will look
up the batch set key corresponding to that mesh in the outer map to find
an inner map corresponding to the single multidraw command that will
draw that batch set. We will know how many meshes the multidraw command
is going to draw by the size of that inner map. Then we simply need to
reallocate the indirect draw parameters and update the pointers to those
parameters within the bins as necessary. There will be no need to do any
binary search or expensive batch set key comparison: only a single hash
lookup and an iteration over the inner map to update the pointers.
This patch implements the above technique. Because we don't have
retained bins yet, this PR provides no performance benefits. However, it
opens the door to maximally efficient updates when only a small number
of meshes change from frame to frame.
The main churn that this patch causes is that the *batch set key* (which
uniquely specifies a multidraw command) and *bin key* (which uniquely
specifies a mesh *within* that multidraw command) are now separate,
instead of the batch set key being embedded *within* the bin key.
In order to isolate potential regressions, I think that at least #16890,
#16836, and #16825 should land before this PR does.
## Migration Guide
* The *batch set key* is now separate from the *bin key* in
`BinnedPhaseItem`. The batch set key is used to collect multidrawable
meshes together. If you aren't using the multidraw feature, you can
safely set the batch set key to `()`.
# Objective

```
to
```rust
#![deny(
clippy::allow_attributes,
clippy::allow_attributes_without_reason,

# Objective
- Contributes to #11478
## Solution
- Made `bevy_utils::tracing` `doc(hidden)`
- Re-exported `tracing` from `bevy_log` for end-users
- Added `tracing` directly to crates that need it.
## Testing
- CI
---
## Migration Guide
If you were importing `tracing` via `bevy::utils::tracing`, instead use
`bevy::log::tracing`. Note that many items within `tracing` are also
directly re-exported from `bevy::log` as well, so you may only need
`bevy::log` for the most common items (e.g., `warn!`, `trace!`, etc.).
This also applies to the `log_once!` family of macros.
## Notes
- While this doesn't reduce the line-count in `bevy_utils`, it further
decouples the internal crates from `bevy_utils`, making its eventual
removal more feasible in the future.
- I have just imported `tracing` as we do for all dependencies. However,
a workspace dependency may be more appropriate for version management.
Some hardware and driver combos, such as Intel Iris Xe, have low limits
on the numbers of samplers per shader, causing an overflow. With
first-class bindless arrays, `wgpu` should be able to work around this
limitation eventually, but for now we need to disable bindless materials
on those platforms.
This is an alternative to PR #17107 that calculates the precise number
of samplers needed and compares to the hardware sampler limit,
transparently falling back to non-bindless if the limit is exceeded.
Fixes#16988.
# Objective
- Contributes to #11478
- Contributes to #16877
## Solution
- Removed everything except `Instant` from `bevy_utils::time`
## Testing
- CI
---
## Migration Guide
If you relied on any of the following from `bevy_utils::time`:
- `Duration`
- `TryFromFloatSecsError`
Import these directly from `core::time` regardless of platform target
(WASM, mobile, etc.)
If you relied on any of the following from `bevy_utils::time`:
- `SystemTime`
- `SystemTimeError`
Instead import these directly from either `std::time` or `web_time` as
appropriate for your target platform.
## Notes
`Duration` and `TryFromFloatSecsError` are both re-exports from
`core::time` regardless of whether they are used from `web_time` or
`std::time`, so there is no value gained from re-exporting them from
`bevy_utils::time` as well. As for `SystemTime` and `SystemTimeError`,
no Bevy internal crates or examples rely on these types. Since Bevy
doesn't have a `Time<Wall>` resource for interacting with wall-time (and
likely shouldn't need one), I think removing these from `bevy_utils`
entirely and waiting for a use-case to justify inclusion is a reasonable
path forward.
# Objective

## Solution
Set the `clippy::allow_attributes` and
`clippy::allow_attributes_without_reason` lints to `deny`, and bring
`bevy_audio` in line with the new restrictions.
No code changes have been made - except if a lint that was previously
`allow(...)`'d could be removed via small code changes. For example,
`unused_variables` can be handled by adding a `_` to the beginning of a
field's name.
## Testing
`cargo clippy`, `cargo clippy --package bevy_dev_tools` and cargo test
--package bevy_dev_tools` were run, and no errors were encountered.
(Except for one warning from bevy_sprite, but I plan to fix that when I
get to bevy_sprite)
# Objective
Optimization for sprite picking
## Solution
Use `radsort` for the sort.
We already have `radsort` in tree for sorting various phase items
(including `Transparent2d` / sprites). It's a stable parallel radix
sort.
## Testing
Tested on an M1 Max.

# Objective
While checking over https://github.com/bevyengine/bevy/pull/17160, it
occurred to me that rust-analyzer will copy the method signature
exactly, when using tab completion trait methods. This includes provided
trait methods that use underscores to silence the `unused_variables`
lint. This probably isn't good for users, seeing as how they'll have to
remove the underscore if they want to use the parameters.
(I mean, they technically don't have to remove the underscore... but
usually you don't keep a leading underscore on parameters you're using.)
## Solution
Changes `bevy_reflect::RegisterForReflection::__register()` to
`#[expect(unused_variables)]`, and removes the underscores from its
parameter names.
## Testing
N/A
# Objective
- `GetPath` `path` related methods allow an empty string as the
parameter, but this is not included as a test or in documentation. This
PR adds both.
- Fixes#13459
## Solution
- Updates the `bevy_reflect` `GetPath` documentation and unit tests
## Testing
- `cargo run -p ci`
Derived `Default` for all public unit structs that already derive from
`Component`. This allows them to be used more easily as required
components.
To avoid clutter in tests/examples, only public components were
affected, but this could easily be expanded to affect all unit
components.
Fixes#17052.
# Objective
Improve DAG building for virtual geometry
## Solution
- Use METIS to group triangles into meshlets which lets us minimize
locked vertices which improves simplification, instead of using meshopt
which prioritizes culling efficiency. Also some other minor tweaks.
- Currently most meshlets have 126 triangles, and not 128. Fixing this
might involve calling METIS recursively ourselves to manually bisect the
graph, not sure. Not going to attempt to fix this in this PR.
## Testing
- Did you test these changes? If so, how?
- Tested on bunny.glb and cliff.glb
- Are there any parts that need more testing?
- No
- How can other people (reviewers) test your changes? Is there anything
specific they need to know?
- Download the new bunny asset, run the meshlet example.

# Objective
- As stated in the linked issue, if a Mesh2D is drawn with elements with
a positive Z value, resulting gizmos get drawn behind instead of in
front of them.
- Fixes#17053
## Solution
- Similar to the change done for the `SpritePipeline` in the relevant
commit (5abc32ceda), this PR changes both
line gizmos to avoid writing to the depth buffer and always pass the
depth test to ensure they are not filtered out.
## Testing
- Tested with the provided snippet in #17053
- I looked over the `2d_gizmos` example, but it seemed like adding more
elements there to demonstrate this might not be the best idea? Looking
for guidance here on if that should be updated or if a new gizmo example
needs to be made.

## Testing
I ran `cargo clippy`, and received no errors.
## Objective
The error `EntityFetchError::NoSuchEntity` has an `UnsafeWorldCell`
inside it, which it uses to call
`Entities::entity_does_not_exist_error_details_message` when being
printed. That method returns a `String` that, if the `track_location`
feature is enabled, contains the location of whoever despawned the
relevant entity.
I initially had to modify this error while working on #17043. The
`UnsafeWorldCell` was causing borrow problems when being returned from a
command, so I tried replacing it with the `String` that the method
returns, since that was the world cell's only purpose.
Unfortunately, `String`s are slow, and it significantly impacted
performance (on top of that PR's performance hit):
<details>
<summary>17043 benchmarks</summary>
### With `String`
### No `String`
</details>
For that PR, I just removed the error details entirely, but I figured
I'd try to find a way to keep them around.
## Solution
- Replace the `String` with a helper struct that holds the location, and
only turn it into a string when someone actually wants to print it.
- Replace the `UnsafeWorldCell` with the aforementioned struct.
- Do the same for `QueryEntityError::NoSuchEntity`.
## Benchmarking
This had some interesting performance impact:
<details>
<summary>This PR vs main</summary>
</details>
## Other work
`QueryEntityError::QueryDoesNotMatch` also has an `UnsafeWorldCell`
inside it. This one would be more complicated to rework while keeping
the same functionality.
## Migration Guide
The errors `EntityFetchError::NoSuchEntity` and
`QueryEntityError::NoSuchEntity` now contain an
`EntityDoesNotExistDetails` struct instead of an `UnsafeWorldCell`. If
you were just printing these, they should work identically.

Use the latest version of `typos` and fix the typos that it now detects

(This link may go stale) https://github.com/crate-ci/typos/issues/1200
# Background
In `no_std` compatible crates, there is often an `std` feature which
will allow access to the standard library. Currently, with the `std`
feature _enabled_, the
[`std::prelude`](https://doc.rust-lang.org/std/prelude/index.html) is
implicitly imported in all modules. With the feature _disabled_, instead
the [`core::prelude`](https://doc.rust-lang.org/core/prelude/index.html)
is implicitly imported. This creates a subtle and pervasive issue where
`alloc` items _may_ be implicitly included (if `std` is enabled), or
must be explicitly included (if `std` is not enabled).
# Objective
- Make the implicit imports for `no_std` crates consistent regardless of
what features are/not enabled.
## Solution
- Replace the `cfg_attr` "double negative" `no_std` attribute with
conditional compilation to _include_ `std` as an external crate.
```rust
// Before
#![cfg_attr(not(feature = "std"), no_std)]
// After
#![no_std]
#[cfg(feature = "std")]
extern crate std;
```
- Fix imports that are currently broken but are only now visible with
the above fix.
## Testing
- CI
## Notes
I had previously used the "double negative" version of `no_std` based on
general consensus that it was "cleaner" within the Rust embedded
community. However, this implicit prelude issue likely was considered
when forming this consensus. I believe the reason why is the items most
affected by this issue are provided by the `alloc` crate, which is
rarely used within embedded but extensively used within Bevy.

Disable debug outlines for hidden and clipped nodes by default and add

# Objective
- Fixes https://github.com/bevyengine/bevy/issues/16556
- Closes https://github.com/bevyengine/bevy/issues/11807
## Solution
- Simplify custom projections by using a single source of truth -
`Projection`, removing all existing generic systems and types.
- Existing perspective and orthographic structs are no longer components
- I could dissolve these to simplify further, but keeping them around
was the fast way to implement this.
- Instead of generics, introduce a third variant, with a trait object.
- Do an object safety dance with an intermediate trait to allow cloning
boxed camera projections. This is a normal rust polymorphism papercut.
You can do this with a crate but a manual impl is short and sweet.
## Testing
- Added a custom projection example
---
## Showcase
- Custom projections and projection handling has been simplified.
- Projection systems are no longer generic, with the potential for many
different projection components on the same camera.
- Instead `Projection` is now the single source of truth for camera
projections, and is the only projection component.
- Custom projections are still supported, and can be constructed with
`Projection::custom()`.
## Migration Guide
- `PerspectiveProjection` and `OrthographicProjection` are no longer
components. Use `Projection` instead.
- Custom projections should no longer be inserted as a component.
Instead, simply set the custom projection as a value of `Projection`
with `Projection::custom()`.
# Objective
- As stated in the related issue, this PR is to better align the feature
flag name with what it actually does and the plans for the future.
- Fixes#16852
## Solution
- Simple find / replace
## Testing
- Local run of `cargo run -p ci`
## Migration Guide
The `track_change_detection` feature flag has been renamed to
`track_location` to better reflect its extended capabilities.
# Objective
- Fix sprite rendering performance regression since retained render
world changes
- The retained render world changes moved `ExtractedSprites` from using
the highly-optimised `EntityHasher` with an `Entity` to using
`FixedHasher` with `(Entity, MainEntity)`. This was enough to regress
framerate in bevymark by 25%.
## Solution
- Move the render world entity into a member of `ExtractedSprite` and
change `ExtractedSprites` to use `MainEntityHashMap` for its storage
- Disable sprite picking in bevymark

## Migration Guide
- `ExtractedSprites` is now using `MainEntityHashMap` for storage, which
is keyed on `MainEntity`.
- The render world entity corresponding to an `ExtractedSprite` is now
stored in the `render_entity` member of it.
# Objective
Remove the `atlas_scaling` field from `ExtractedUiItem::Gylphs`.
It's only ever set to `Vec2::ONE`. I don't remember why/if this field
was ever needed, maybe it was useful before the scale factor clean up.
## Migration Guide
The `atlas_scaling` field from `ExtractedUiItem::Gylphs` has been
removed. This shouldn't affect any existing code as it wasn't used for
anything.
# Objective
Tab navigation can fail in all manner of ways. The current API
recognizes this, but merely logs a warning and returns `None`.
We should supply the actual reason for failure to the caller, so they
can handle it in whatever fashion they please (including logging a
warning!).
Swapping to a Result-oriented pattern is also a bit more idiomatic and
makes the code's control flow easier to follow.
## Solution
- Refactor the `tab_navigation` module to return a `Result` rather than
an `Option` from its key APIs.
- Move the logging to the provided prebuilt observer. This leaves the
default behavior largely unchanged, but allows for better user control.
- Make the case where no tab group was found for the currently focused
entity an error branch, but provide enough information that we can still
recover from it.
## Testing
The `tab_navigation` example continues to function as intended.
# Objective
Resolves#17064
## Solution
- Bevy no longer converts asset file extensions to lowercase before

- The changes were tested on Linux
As far as I know, Windows has a case-insensitive file system by default,
so case-sensitive asset file extensions are probably bad practice in a
game. But we should be case-sensitive everywhere or handle asset paths
completely case-insensitive.
Before this PR:
* asset loader extensions are case-sensitive
* asset file names are case-sensitive
* asset file extensions are converted to lowercase ⚡
Now everything should be case-sensitive
# Objective
Following #16876, `bevy_input_focus` works with more than just keyboard
inputs! The docs should reflect that.
## Solution
Fix a few missed mentions in the documentation.
Also add a brief reference to navigation frameworks within the module
docs to help give more breadcrumbs.
# Objective
- Support more ergonomic conditional updates for types that can be
modified by `clone_into`.
## Solution
- Use `ToOwned::clone_into` to copy a reference provided by the caller
in `Mut::clone_from_if_neq`.
## Testing
- See doc tests.
